What is the first step in the Order of Operations?

Back

Parentheses: Solve expressions inside parentheses first.

Front

What is the second step in the Order of Operations?

Back

Exponents: Calculate powers and roots.

Front

What is the third step in the Order of Operations?

Back

Multiplication and Division: Perform these operations from left to right.

Front

What is the fourth step in the Order of Operations?

Back

Addition and Subtraction: Perform these operations from left to right.

Front

Solve: 3 + 5 × 2

Back

13 (First multiply 5 × 2 = 10, then add 3).

Front

Solve: (4 + 6) ÷ 2

Back

5 (First add 4 + 6 = 10, then divide by 2).

Front

Why is the Order of Operations important?

Back

It ensures that everyone calculates expressions in the same way, leading to a single correct answer.

Front

Identify the error: 8 - 2 + 3 = 9

Back

The error is in the order of operations; subtraction should be done first.
